Search 42 U.S.C. § 7476 : US Code - Section 7476: Other pollutants

(a) Hydrocarbons, carbon monoxide, petrochemical oxidants, and
nitrogen oxides
In the case of the pollutants hydrocarbons, carbon monoxide,
photochemical oxidants, and nitrogen oxides, the Administrator
shall conduct a study and not later than two years after August 7,
1977, promulgate regulations to prevent the significant
deterioration of air quality which would result from the emissions
of such pollutants. In the case of pollutants for which national
ambient air quality standards are promulgated after August 7, 1977,
he shall promulgate such regulations not more than 2 years after
the date of promulgation of such standards.
(b) Effective date of regulations
Regulations referred to in subsection (a) of this section shall
become effective one year after the date of promulgation. Within 21
months after such date of promulgation such plan revision shall be
submitted to the Administrator who shall approve or disapprove the
plan within 25 months after such date or promulgation in the same
manner as required under section 7410 of this title.
(c) Contents of regulations
Such regulations shall provide specific numerical measures
against which permit applications may be evaluated, a framework for
stimulating improved control technology, protection of air quality
values, and fulfill the goals and purposes set forth in section
7401 and section 7470 of this title.
(d) Specific measures to fulfill goals and purposes
The regulations of the Administrator under subsection (a) of this
section shall provide specific measures at least as effective as
the increments established in section 7473 of this title to fulfill
such goals and purposes, and may contain air quality increments,
emission density requirements, or other measures.
(e) Area classification plan not required
With respect to any air pollutant for which a national ambient
air quality standard is established other than sulfur oxides or
particulate matter, an area classification plan shall not be
required under this section if the implementation plan adopted by
the State and submitted for the Administrator's approval or
promulgated by the Administrator under section 7410(c) of this
title contains other provisions which when considered as a whole,
the Administrator finds will carry out the purposes in section 7470
of this title at least as effectively as an area classification
plan for such pollutant. Such other provisions referred to in the
preceding sentence need not require the establishment of maximum
allowable increases with respect to such pollutant for any area to
which this section applies.
(f) PM-10 increments
The Administrator is authorized to substitute, for the maximum
allowable increases in particulate matter specified in section
7473(b) of this title and section 7475(d)(2)(C)(iv) of this title,
maximum allowable increases in particulate matter with an
aerodynamic diameter smaller than or equal to 10 micrometers. Such
substituted maximum allowable increases shall be of equal
stringency in effect as those specified in the provisions for which
they are substituted. Until the Administrator promulgates
regulations under the authority of this subsection, the current
maximum allowable increases in concentrations of particulate matter
shall remain in effect.
